Application )Sled July 15,

Our invention is a laying out tool, particulurlyadapted for marking pipes in order tok cut vseine to nialre angular connections of the sections fof the pipev out. y A

An object `of our invention is the vconstruen tion of a. laying out tool which nieybe positioned on e. .pipe ortho like to be out, this tool hevingla pair of -ern-is which iney be p0- s'itioned et the ang-le of a linishedpipesconneetioiigend having ineens `to merk the pipe @reform -e 4marking rule whereby the pipe cen he entend afterwards weldedon the line.

Itisthe custom in some 'types of piping work-toforrn iingulzir connections,` elbows for the like by cutting a long' section of pipe on an `single rele-tive to the exis of tli`e pip`e and utilizing thev two i sections cut to weld these together,- forining/tlie desired ingle or elbow. This typeof joint isunguler instead ofl be; ing cuived and insybe'rnade of any desired ,an-glei i i A particular object of our invention is formi-ng a laying out tool with a lpnir of legs, either one of which may be' placed on the pipe to be` out, extending longitudinally thereof and having e p'rotractor device mounted on one of the legs withepointer slidably mounted on a guide rod having ineens to retain the guide rod in the desired position to biseet the angleniede by the two` legs. y 'i y In edd-itfion tothe above construction our invention comprises a` tape mounted in alineinent with the guide' rod so' that the tape may be drawn around the pipe at the desired an gie end e marking line: indicated thereon.

Our laying out tool besides being adapted for the purpose above mentioned is provided with a spirit level to be utilized in lsying out or cutting pipes for i horizont-al connection or the like, graduated in zi measuring scale and preferably the legs are foriiied with fr hinged or folded connection.` We :ilse vpro vide the legs of the laying out tool with prongs so that the device may be used ss u pair of dividers. i l

Our invention is constructed substantially es follows, having reference to the drewings,` in which;

This rod has :in extension 15 beyond therethrough. Aptape container i7 isrfigidly secured to the guide rod in any suit'ible inginner, thatl shown being by ineens of the clninping freine` i8.,

i`lie tape i9 is preferiibly inou'nte'd on al drum, spring" controlled iii the usual iiianne'i' und extends through the aperture i6 for af? purpose hereunder set forth. A. pair of' linksV 20 ,endiQl are the legs by` pivot pins slidnble coller 23 und pivot pi'nsQei, the' free ends of the links forming e slidiible connection with the guide rod. 'llie back of the tape mounting is provided with an indicating arrow 25 pointing to the preti-actor. ylhe links QOsiid E21V are each preferably formed of two being one on euch side of the leg structures.

rllie nizinner of using our laying' outn tool' in cutting pipe is substantially asfollows: i

Presuining s longl pipe indicated by the numeral 26 is to be out on an angle indi'- ceted by the numeral 27 so that thesections of the pipe f n'iziy be forni l s welded pipe nuniernlQS indottedlines, the laying out toolpis plecedon the pipe, one of th'e legs extending longitudinally thereof. The de pivot i the pivot bolt with an' aperture pivotell'y connected to 122 und by ineens olf si straps, there connected together and joint indicated by the.`

sired angle of cut is indicatedl on the protractor,A the legsbcing opened until the pointer points at the desired angle andhence the guide rod bisects the angle between the two legs.

encircled around the pipe. ln some cases it will be necessary to aline the tape' by the eye with the guide rod, but in usual cutting this is not necessary.

A pencil or chalk niark or tlielike may then be made around the pipe,` using .the tape as the guide. 'lhe tape may then be rewound in the casing andthe pipe cut in any suitable manner on the line indicated, the end cut ott welded to the other` part at the angular joint; thereby forming an angle, elbow or the like. i i s v l, Presuming a Apipe occupies a somewhat vertical or sloping position and it is desired to extend the pipe therelroin at a horizontal angle, one of the legs may be placed along the iiXed or standing pipe and the other leg adjusted by the spirit levelto show 'a horizontal reading. VThen the tape may be applied to the pipe and when cut and the cut olf end welded to the upstanding pipe, will givea horizontalangular connection. Other adaptations of my invention will be appar ent.

It is also obvious that the rule may be utilized for various measurements in connec tion with work on pipes or otherwise and that the device may be utilized as a `divider by clamping the thumb nut 9 with the prongs any desired spaced distance apart `and hence forming a compass or -tlie like. i i ,i

We have illustrated the links 2O and 2l of suoli length so that the two legsiiiay be ezttended out into yalinenient. Howeveig in many cases this will not be necessary and they may be made considerably short, it most of the angles formed are less than 120 degrees.

It will be apparent that the structural details to forni our laying out tool may be considerably changed in making tools for diir ferent speciiic purposes. Therefore the general construction and specific details may be departed from. Such changes however,` will be within the spirit of our invention as set forth in the description, drawings i and claims.

It is obvious with our invention that the links Q() and `2l can be made oi di'erent lengths and a different pivotal connection with the legs so that the angle formed by the guide rod with the legs may divide the anglebetween the legs in any desired proportion` The proportion shown bisects such angle. Moreover, it is obvious that il our device is to be utilized as a protractor that the pair of legs notliaving thegprotractor may be omittedand have means toclainp The tape is then drawn out of the i' casing, passed through the aperture 1G and `being rotatedon its axis and the guide rod at the desired angle as indicatedby the arrow.
